What depth of water is used for the edge of the Continental Shelf?

Explanation:
The depth used to mark the edge of the continental shelf is the line that charts the boundary between the shallow shelf and the steeper continental slope. This boundary is conventionally shown on nautical charts by the hundred-fathom line. It indicates a transition zone where the seafloor drops more steeply from the relatively flat shelf into deeper ocean waters. The other depth lines are either much shallower (closer to shore) or much deeper (farther offshore) and do not represent the standard shelf edge.
